A system of linear higher-order of differential equations takes too long

Hello, I am trying to solve a system of differential equations as below

Unfortunately it takes too long and puts a lot of strain on the computer. Could someone advise me how to do it to make it optimal. Maybe one of you could try to solve this problem on your computer? Kind regards Marcin

If I manage to solve the problem I will let you know ;-) I will do it maybe in a slightly different/engineering way not directly but I will do it strict.

I didn't like the hint ;-) I need a close/analytical solution. Thank you for your interest.

In fact, this system of equations cannot be solved using Mathematica.

Maple 2022.2 can solve, but you won't like the answer.

See attached PDF file.
